We have developed a catalytic protocol for Diels-Alder reaction using trialkylphosphonium oxoborates as oxyanion hole catalysts. The reaction can be operated under ambient conditions. Dienes could easily polymerize under acidic condition. Nonetheless, these acid-sensitive substrates are compatible with the catalytic protocol and the reaction scope covers a wide range of substrates.
我们开发了一种使用三烷基磷鎓氧硼酸盐作为氧阴离子空穴催化剂的狄尔斯-阿尔德反应催化方案。该反应可以在环境条件下进行。二烯在酸性条件下很容易聚合。尽管如此,这些酸敏感底物与催化方案兼容,反应范围涵盖广泛的底物。
